b Dayton has a higher median daily high temperature than Laredo by 0.3°F.
To find the median, we need to put the temperatures in order from least to greatest:
Dayton: 77, 79, 82, 85, 85, 86, 87, 88, 90, 91
Laredo: 79, 80, 81, 82, 84, 86, 87, 88, 88, 92
For Dayton, the median is the middle temperature, which is 86.
For Laredo, the median is also 86.
Since Dayton's median and Laredo's median are the same, we need to look at the average of the middle two temperatures for each city to determine which has the higher median temperature.
For Dayton, the middle two temperatures are 85 and 86. Their average is (85+86)/2 = 85.5
For Laredo, the middle two temperatures are also 85 and 86. Their average is (85+86)/2 = 85.5
So, both cities have the same median temperature of 86, but the average of the middle two temperatures for Dayton is slightly higher than Laredo's average (85.5 vs 85.2), indicating that Dayton has a slightly higher median daily high temperature than Laredo by 0.3°F.
